Johnnie Johnson

Really sad news for old school fans.

Rock n' Roll Hall of Famer Johnnie Johnson, 80, has died in his home in St. Louis. You may not know the name, but, for sure, you've heard him play. He was Chuck Berry's piano player and collaborator for gangs of hits like "School Days" and "Back in the U.S.A."

Chuck even wrote a song about him: the Rock n' Roll National Anthem - Johnny B. Goode.
